SHUTTLE-ACTUATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 563,345, dated July '7, 1896.

Application filed July 7,1894. Serial No. 516,839. (No model.)

To a, whom it may concern.-

Be it known that we, J OSEPH F. WICKS and BOZIL S. ROY, citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in a Shuttle-Actuating Mechanism for Looms, of which the following is a specification containing a full, clear, and exact description of our invention, and accompanied by drawings, forming apart of the specification, in which Figure 1 is ahorizontal sectional view showing the lower portion of a loom containing that portion of the shuttle-actuating mechanism which embodies our invention, the several operating parts being shown in their normal positions when the loom is in operation. Fig. 2 represents the same view as shown in Fig. 1, but with the rocking picker-shafts shifted so as to carry the shoes attached to the picker-shafts out of the path of the sweeps carried upon the rotating shaft of the loom. Fig. 3 is a vertical sectional view on line 3 3, Fig. 1, showing a portion of the mechanism by which the picker-shafts are shifted. Fig. 4 is a central sectional View of one of the sliding blocks in which one of the pickershafts is journaled. Fig. represents a portion of the picker-shaft-shifting mechanism, on a larger scale than that represented in Fig. 3, with the parts shown in position when the picker-shafts are held in engagement with the driving power; and Fig. 6 represents the same parts as shown in Fig. 5, but in the position assumed when the, picker-shafts have been carried out of engagement with the driv- Referring to the accompanying drawings,-

A A denote the side frames of a loom, and

A A front and rear girths connecting the side frames.

B is a rotating shaft carrying the radial 5 5 arms or sweeps B, the free ends of which are provided with rolls B journaled upon fixed studs held in the arms B.

C 0 represent the rocking picker-shafts journaled .in bearings at their ends and having arms or shoes 0, arranged in position to be struck by the rolls B as the sweeps are rotated by the shaft B. The rocking pickershafts C are provided with arms 0 connected with the picker-staves D by straps D in the usual and well-known manner. As the shaft B rotates, the shoes 0 will be struck by the rolls B twice during each rotation of the shaft B, depressing the shoes D, thereby imparting a short, quick rocking 'motion to the pickershafts O, which through the arms 0 and straps D will communicate a quick angular movement to the picker-staves D, causing the shuttle to be thrown across the raceway.

The purpose of our present invention is to provide means for disconnecting the pickershafts O O by carrying the shoes 0 out of the path of the rolls B so the rotation of the I shaft B will cease to actuate the pickerstaves D, and also to provide means whereby the disengagement of the picker shafts G will be made to simultaneously operate a shipping mechanism which can be adapted to reverse the motion of the loom, as hereinafter described, or to reverse the motion of some of its operating parts, as, for example, the pattern mechanism by causing the pattern-chain to run backward instead of forward.

It is not new to disengage the shuttle-actuating mechanism from the driving power by carrying the shoes 0 out of the path of the rolls B but the particular mechanism by which we accomplish this result, so far as we are aware, is new, and we also consider it to be new to provide means whereby the disengagement of the shuttle-actuating mechanism is made to simultaneously operate a shipping mechanism.

The forward ends of the picker-shafts O O are held by blocks E E, attached to thegirth A, and the rear ends are supported by blocks F F, sliding horizontally in Ways F upon the rear girth A Held within spherical sockets in the blocks E and F are balls G, one of which is shown in Fig. 4, those in the remaining blocks being duplicates, and the ends of the picker-shafts (l C are j ournaled in the balls G, so as to slide sufficiently therein in order to permit a slight angular movement of the picker-shafts O by means of the rotation of the balls G within their sockets. The sliding blocks F F are attached by links H H to the radial arms II, projecting from the opposite sides of a plate H pivoted upon a stud H held by the rear girth A The plate H is provided with a notch II", which is engaged by a spur I, projecting radially from a plate I, attached to a shaft 1 journaled in bearings on the girths A and A and provided with a hand-lever 1 by which the shaft I is rocked. The plate I is provided with concentrically-curved surfaces P1 and projecting shoulders I I and the plate 11 is provided with concave surfaces 11 11", adapted to fit the curved surfaces I I. The rotation of the shaft 1 imparts an angular motion to the radial arms 11 H, rocking them back and forth between the positions shown in Figs 5. and 6, the angular movement of the arms 11' being limited by the engagement of the plate H with the shoulders I I \Vhen the arms H. H are in the position shown in Figs. 3 and 5, the sliding blocks F F are drawn toward each other so as to hold the picker-shafts C 0 parallel and at right angles with the rotating shaft 13, as shown in Fig. 1; but when the arms II II are in the position shown in Fig. 6 the sliding blocks F F are moved from each other, carrying the rear ends of the picker-shafts and bringing them into the position shown in Fig. 2, with the shoes I) held out of the path of the rolls 13 One of the sliding blocks F F is provided with a projecting arm J, which, as the block is moved to disengage the shuttle-actuating mechanism, is brought against the end of a pivoted lever J, thereby imparting an angular movement to the lever, which can be made to actuate any desired shipping mechanism. In the accompanying drawings the end of the lever J is pivoted to a sliding shipping-bar J carrying belt-eyes JZinelosing the drivingbelts J and J which run in opposite direc tions and are alternately shifted from the loose pulleys J to the tight pulleys J on the shaft 15 by the reciprocating motion of the shippin g-bar. The sliding motion of the boxes will actuate the lever J to slide the shipping bar J 2 in one direction, and its motion is reversed, when the lever J is released, by means of a spring J attached at one end to a fixed portion of the loom and at its opposite end to a pin J ,carried by the sliding shipping-barf.

The arrangement of oppositely running belts and shipping mechanism, as shown in the accompanying drawings, is represented for purpose of illustrating one method of practically applying the angular movement of the lever J to actuate a shipping mechanism by which the motion of the loom is reversed; but it will be obvious that instead of reversing the motion of the loom by means of a shipping-bar and oppositely -running belts the same result can be secured by the application of any known shippingmechanism to actuate a friction or other clutching mechanism, or the shipping mechanism, instead of being directly connected with the driving power of the loom, can be employed to reverse the motion of a pattern-chain, the reversing of the motion of the patterlrcliain being a well-known and commonly-practiced method employed for the purpose of reversing the action of the harness-frames in order to allow a portion of the woven fabric to be picked out.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination with the rocking shafts O, 0, provided with movable bearings F, F, of a shipping mechanism connected with said movable bearings and consistin g of a notched plate IPpivoted upon a fixed stud II and having radial arms H,I I',links connecting said ra dial arms with said movable bearings, rocking shaft 1 plate I attached to said rocking shaft I and having a spur I engaging said notched plate, said plate 11 having concave edges II, II, and said plate I having convex edges 1 and shoulders 1 by which the motion of said plate 11 is limited, substantially as described.

2. In a loom, the combination with a rock ing picker-shaft 0 held in a movable bearing capable of a sliding motion, whereby the position of said picker-shaft is varied, of a pivoted lever arranged in the path of said movable bearing and a shipping mechanism operatively connected with said pivoted lever by which the movement of said picker-shaft will actuate said shipping mechanism, substantially as described.
